I red an article a few month ago about a jucier from the los angelos area who would sit in those warm water tubs for liek 2 hours and sleep. the only thing is he said it was like giving your muscles 8 hours of sleep for every 2 hours you spent in there. I forgot the name of the tub but want to look into it i know its the same type of things hippies used and is considered a hollistic remedy anybody have any experience with this.
